Mycena. 

 sect. ii. basipedes. 



131. Mycena bonksiae, n. sp. — Pileus up to \ inch, in 

 diameter, convex, then nearly plane, viscid, sulcate-striate 

 to near the centre, which may be depressed, covered with a 

 pruinose downiness except in the centre, greyish-white 

 becoming brownish, centre darker. Gills not or scarcely reach- 

 ing the stem to adnate, moderately close, edges not serrate, 

 greyish-white. Stem short, less than \ to -f inch high, 

 shining, smooth, not definitely viscid, whitish with a slight 

 greyish tint, attached by a small disk to the base of Banksia 

 trunks, dead or living; we have also found it on dead wood 

 other than Banksia. No smell. Spores subspherical, often 

 with a large "nucleus," 6'8 to 9, 8'5 x 7, 8x5, 6x5 jul, etc. 

 No cystidia. Mosman, April, 1915; Neutral Bay, April, 

 1915 (pileus conico-convex, pileus and stem with a glaucous 

 bloom, lavender-grey, pileus widely sulcate ; gills few, adnate, 

 widely separate, greyish-white ; stem swollen below) ; Neutral 

 Bay/April, May; National Park, N.S. Wales, July, 1916; 

 Bradley Head, Sydney, May, 1917. (Miss Clarke, Water- 

 colour 52; Herb., J. B. C, Form. Sps 55 and 63.) 



Pileus ad 1'25 cm. latus, convexus, deinde subplauus, viscidus, 

 sulcato-striatus, pruinosus, subcinereo-albidus, deinde sub- 

 fusco tinctus. Lamellae subadnatae ad adnatae, subcon- 

 fertae, marginibus non serratis, cubcinereo-albidae. Stipes 

 brevis, 1"25 (minus) cm. altus, nitidus, glaber, subcinereo- 

 albidus, disco parvo. Sporae subsphericae, 6'8-8, 8'5 x 7, 

 6x5 ft. 



We have named the species banksiae from having 

 frequently found it growing on the trunks of various 

 Banksias. (PI. xxix., fig. 3.) 



SECT. III. GLUTINIPEDES. 



132. Mycena coccineus, n. sp. — The following beautiful 

 little species seems referable to the genus Mycena. Speci- 

 mens exhibit a tendency to revive when moistened, though 

 this feature is not so definite as in the typical Marasmius. 

 The gills, adnate when young, also tend to be definitely 

 though slightly decurrent when old, suggesting Clitocybe, 

 whilst their edges are rather thick, thus approaching 

 Caritharellus. In Cooke's illustrations we can find no species 

 at all resembling it. By its darker denticulate edge to the 

 gills it is probably related to Mycena strobilina and M. rosella, 

 though on account of the glutinous stem when moist we place 

 it in Mycena under Crlutinipedes : — Pileus | inch in diameter, 

 hemispherical to convex, occasionally dimpled or with a slight
